The last one I delivered was approximately split in half. When taken apart, both pieces were the same height and width. The top Piece sticks out farther than the bottom piece for the lights. You can take what you know about the base width and height and use it as a reference when figuring out the rest, can't you? For example, if the top depth is about 1/2 the bottom, thus divide the bottom depth by 2. You should get pretty close. Or, I know a bar in Texas where you could show up with a tape measure....
